ELECTROM ECHANICAL LOCK.

SPECIFICATION forming part of Letters Patent Hui-608,319, dated August 2, 1898.

Application filed September 9, 1897- Scrial No. 651,016. (No modeli) I To all whom it, may concern:

Be it known that I, HENRY GUY CARLETON, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Electromechanical Locks, fully described and represented in the followin g specification and the accompanying draw- 1 ings, forming a part of the same.

This invention relates to that class of locks which is provided with electrical means for unlocking the same; and the invention consists in an improved construction whereby a lock having no exterior means for moving its boltwork has its'bolt secured by a keeper electrically withdrawn and which look has pointed out in the claims.

i A practical embodiment of this invention is illustrated in the accompanying drawings, in which like characters of reference indicate correspondingparts, and arrow-heads connected with section-lines indicate the direcvtion in which the picture is seen.

In said drawings, Figure'l is an elevation of a portion of a door and its jamb, showing my improved look attached thereto, some of 'theexterior parts being broken away to ex pose others. Fig. 2 is a horizontal sectional View of the same, taken on the line 2 2 of Fig. 1; Fig. 3 is an inside view of the door, illustrating the parts of the lock that show on that side. a Fig. 4 is an enlarged sectional' view of the lock, taken on line 4 4 of Fig. 6, looking to the left as the arrow-head points or in a direction toward the back of the lock;

Fig. 5 is a similar view taken on line .5 5' of Fig. 6, looking to the right as the arrow points or in a direction toward the front of the lock. Fig. 6 is a vertical'sectional elevation taken on the line 6 6 of Fig; 4, one of the disk-op,- erating mechanisms being shown in section and the other in elevation. Fig. 7 is a horizontal sectional view taken on line 7 7 of Fig.

As the preferable form of'niy invention I have shown a lock comprising two like sets of electric-current-controlling disks and operating mechanisms, and in describing'the same it will be understood that a description of corresponding parts of one setwill apply to both.

To exemplify this invention, an ordinary mortise-lockO has been selected, said lock being secured to the door A in a common manner and 'so' as to cooperate with parts secured to the jainb B. \Vithin the casing of the lock an upper disk D and a lower disk E are mounted, so as to be rotated by exterior knobs 50, which disks are preferably made of brass because of its conductive capacity. The face, of each of these disks is provided with a circularly-arranged series of countersunk recesses suitably designated, as by the numbers 0 to 23, each of which recessesv is adapted to be engaged by an indicator-pin, as 24, which is preferably springretracted. Each disk is provided, say, at a point corresponding with its recess 0, with a non-conductingplug, as 26, of hard rubber or other suitable insulating material inserted in its periphery;

Theconductive disks D E are each carried by metal spindles, as 28, upon each of which spindles is'monnte'd a non-conducting disk, as 29, having an extended hub, as 38, through which the spindle passes. These disks 29 are made of suitable insulating material, preferably hard rubber, and are pinned to the spindles, so as to partake of all of-the movements. of the .disks 1) E, respectively. The upper bar 31, so inserted-in and fastenedto it that atthe periphery of the disk, (seeiFigs. 5 and 9,) and the lower disk 29 is-provided with a' similar metalconducting-bar -32,"-which has one-end extended to and exposed at the periphery of thev disk and the other end arranged to contact with the spindle; 28 of the disk E.. The hub 33 of each disk 29 carries fast thereto a ratchet-wheel 34, that is enwhich to an is held forward to duty by means of a spring 38, so that its pawl will normally be held in engagement with the ratchet-wheel 34.

Between each ratchet-wheel 34 and the disk 29,which carries it,there is a helical spring 39, the inner end of which is attached to the hub 33 of the disk, while its outer end is secured to an ear projecting within the lock-casing, as shown in Fig. 5. The spring 39 for each disk 29 retains said disk and the parts connected therewith in normal position and returns it to snch'position after each operation.

Each ratchet-wheel 34 is provided with a pin 40, that engages the single tooth 41, carricd by a small disk 42. The disks 42 are at the inner ends of spindles 66, the outer ends of which are squared and support settingwhcels 43, each of which carries a pin 44, that is arranged to en ter the circular series of holes 45, formed in dial-plates 46, each of which dial-plates is marked on its outer face with numbers corresponding to the position of its holes4c5, as is shown in Fig. 3, and which holes 45 correspond in position with the countersunk recesses in the disks D E. These dialplates 4L6 are held stationary, as by means of hollow shanks, which are screwed fast to the lock-casing, as shown in Fig. 6, and thus form a bearing for the spindles 6G. The settingwheels 43 are held in place on the spindles 6G by means of the flanged heads of holdingscrews 73, which enter tapped holes in the spindles 66. Each wheel 43 is housed and protected by a cover ll, screwed or otherwise fastened to the door, thereby keeping the different parts from view and also giving a finished appearance to the inner surface of the door. From the face of each disk D and E there central! 'projects a sleeve 48, that is jonrnaled in the casing of the lock and which is provided with a mnltifaced socket to receive the similarly-shaped inner end of an operating-spindle 75. These spindles are provided with actuating-knobs 50, and their inner ends are engaged with the said sockets, so that the companion disks D and 29 and E and 2!) maybe rotated when desired and their appurtenances may be actuated as required. The spring-seated indicator-pins 24 are mounted in such a manneizas to be capable oi a rotative as well as a longitudinal movement, and each has a milled head to enable it to. be readily rotated by ones fingers.

F ich ,in '4 carries a rock-arm 25, that is cted with the ratchet-bar 36 by means connecting-rod 6i and pivots, by which a rotative movement of a pin 24- will ope... ate to throw the ratchet-bar 36 0ut of ,en-

gagement with its ratchetdvheel 34 and in order that these pins 2% ma be moved longitudinally without affecting the rock-arms from a- 25 they are 7 the conductive disk D and at slotted, as at 60, to embrace the pin 59, by which the hub of the rock-arm 25 is conneri -.d to them, as shown in Figs. 6 and 8.

The inner or hearing end of each pin 24- is rounded, so as to enable it not only to snugly enter within the correspondingly-shapcd rccess cut in the disk, but be readily disengaged therefrom when a rotative movement of the disk tends to force the pin outward, aided by its spring against the pressure exerted by the operator as he turns the disk D or E with one hand and feels the passing rccesses with the other.

The jamb ot' the door is cut away to receive an electromagnet M, and its pivoted armature 69 extends upward to about the center of the lock, with its free end in line with the bolt G. At its extreme upper end the armature 69 carries a keeper 70, which extends through the jamb of the door and projectsbeyond the outer end of the bolt G, being held normally in this position by a spring 71, this keeper then engaging or intercepting the bolt G and a lug on the face of the lock, thus acting to lock the door closed or prevent its being opened. As the outer end of the bolt G is in line with the outer casing of the look a recess'72, extending from the lug 80, is formed in the outer casing of the look (see Fig. 2) to allow the keeper T0 to project inwardly from the jamb beyond the end of the bolt and also permit it to be nnobstructedly passed, it need be.

To free the bolt G and lug 7O mechanically to unlock the door, the ordinary door-knob' 62 has a spindle 63 extending from the inner surface of the door to the outcrcasing of the lock, and its spindle 63 passes through an elongated slot (37 in the bolt G and is provided with a dog 64, that engages in a notch 68, with which the bolt G is provided, by which arrangement the bolt may be thrown inwardly to admit of the door being opened from the inside.

Thelock is provided with means for makingand breaking an electrical circuit by which this magnet M may be energized to perform the unlocking operation, as follows: Conducting contactsprings 52, 53, 5t, 55, 56, 57, and 58 58 are arranged within the lock-casing at suitable points for operation, as follows: The springs 53 54 contact at suitable times with the opposite ends of the conductorbar 31, that extends across the upper non-conducting disk 29 and otherwise run in contact with its nonconducting peripher The spring 55 is positioned so as to contact with times rests upon its insulating-plug 26. The spring 56 contacts at suitable times with the conductor-bar- 32, that extends from the periphery of the lower disk 29 to its spindle 28, and otherwise runs in contact with the non-conducting pe-' riphery of that disk. The spring 5'? is positionedso as to contact with the periphery of the conductive disk Band at times rests upon its insulating-plug 20. The springs 58 58 are the periphery of arranged toconstantly press upon the spindies 28 28'and are connected by the wires m p. The spring 52 is so positioned within the lock-casing that it may be engaged by a push-button 51, that is mounted in the door, so that it may be moved inwardly to perform "that duty.

A battery X, placed in a suitable adjacent locality, is connected by a conductor (1 with the magnet M, and thence by aconductor ate the contact spring 53. The contact-spring 54 is connected by a conductor 0?. with the con-. tact-spring 56, and thespindles 28 28 of the disks are connected, respectively, by contactsprings 58 58 through conductors m p, which latter connect by a wire Z with; the contactspring 52. The contact-springs 55 57 areconnected together by conductorss t, and the conductor sconnects through magnetNof an alarm-bell, and thence to the battery X.

The electrical operation of the lock will now be explained. As illustrative of the mode of setting the combination of the, lock the operative numbers selected are 4 for the disk D and l2 for the diskE. The cap H is first removed to expose the dial-plate 46 and the wheel 43. The screw 73 is then loosened to enable the wheel 43 to be withdrawn far.

enoughto release its pin 44 from engagement with the dial-plate and permit its rotation. The knob 62 will then be turned to the left (see Fig. 3) and through its spindle ending 64 will draw the bolt G inwardly, and'through its shoulders 37 this movement ofjthe bolt G will swing the bars 36 and each dog 35 from engagement with the ratchet-wheel34, thus permitting the disks D and'29 to rotate freely,

" and while this knob is held the wheel 43 is vwithdrawn and turned to the left until a proper position-indicated by the pointer is reached for its pin 44 to enter the hole numbered 4 in the dial 46, whereupon the screw 73 is returned to fasten the parts in place and the knob is released. the wheel 43 to 'the'left it carries with it the disk 42 and its stop 41, and as the ratchetwheel 34, together with the disk 29, are then free to revolve, impelled by the action of the spring 39, thcy'will rotate (the pin 40 following the stop 41) until the point is reached at which the stop 41 is arrested by the pin 44 on and becoming the initial point,and it is from this initial point that the step-like movements of each disk must be made equal numerically to the number upon which the disk is set to bring that disk into operative position to enable the unlocking operation to be performed.

spring 56.

In thus turning.

To perform this unlocking operation, the operator gently pressing the pin 24 inwardly by one hand with the other rotates the coinvpanion disk by means of the knob 50, and

while doing so the in-and-out movement of the pin 24, as it enters and leaves the recesses in the disk, enables him to count the number of recesses passing the pin. He continues to rotate the diskuntilfour of these openings have passed the pin, 4 being the combinationnumber of the disk D. By stopping this movement of the disk after four openings have thus passed the pin 24 will bring the insulatingblock-or circuit-breaker 26 of disk D into engagement with the contact-spring 55, and as the non-conducting disk 29 is rotated with the disk D it will also bring the opposite ends of the conducting-bar 31, which is carried by the disk 29, into engagement with the spring contacts 53 54.v The disk D is now held in this position against the returning action of. the spring 39 by the dog 35 of the bar 36. The operation of the disk E is the same as that of disk D,except 'that twelve of the openings must pass the pin 24, that being the illustrative combination-number for the disk E. The rotative movement of the disk E, however, brings its circuit-breaker 26 into engagement vwith spring-contact 57, and its companion non-conducting disk 29, rotated with it, brings the conducting bar 32, carried by the disk 29, into engagement with contact- The mechanical combination is now complete and the circuit-conductors properly set to accomplish the electrical unlocking action. The circuit-maker or push button 51 now being pressed makes contact with plate 52 and closes the circuit which is then established from the battery 0; through wires Z m, spindle 28 of disk E, bar 32 of lower disk 29, contact-plate 56,wire a, conswing the bars 36 and throw the dogs 35 out of engagement with ratchet-wheels 34, thus breaking the circuit and allowing the disks D E and their companion disks 29 29 to-be returned by their springs 39 to the initial points limited by the steps 41 and the keeper returned into engagement with the bolt.

Should the person rotating the disk D E by means of the knobs 50 make a mistake in setting either of the disks by turning it beyond the proper nul'nber, he may return said disk to its initial position by rotating the finger-piece 24 corresponding thereto so as to rock'thc bar 36 out of engagement with the ratchet 34, when the disk D or E, as the case may be, will return to its initial position by the spring 39. The connections for so moving the bar or bars 36 upon the rotation of the finger-piece 24c consist, as before stated, of the rock-arm 25, connected to saidfingerpiece, and the link 61, connecting said rockarm with the bar 36.

In any of the cases stated below should the circuit-eloserorpush-button 51 be pressed the alarm-bell 0 will ring if thedoor is locked and the combination oif. If the disk E is on the right combination and disk D is on the wrong combination, the circuit will be closed through the wires Z 2, leading to the stud 28 of disk D, through that disk to contact 55 and a wire .9 to bell-magnet N, and thence to battery 0;. If disk D be on the right combination and disk E on the wrong combination, the circuit is closed through wires Z m, stud 28 of disk tact 57, through wires t s to bell-magnet N, and thence to battery 00.

It will be observed that this construction of lock is such that when the bolt is in look ing position the locked condition is maintained solely by the outward protrusion of the keeper and that when said keeperis withdrawn the door carrying the lock is free to be opened notwithstanding the protruded position of its bolt. So constructed no matter how the bolt mechanism is thrown into position for locking the door-as, for instance, by an ordinary kcy-the unlocking may be accomplished by the movement of the keeper through the electrical appliances, whereby upon making circuit to energize the keeperoperating magnet M the unlocking may be etfected.
